5%283a-8%29=15a Start with the given equation.


15a-40=15a Distribute.


15a=15a%2B40 Add 40 to both sides.


15a-15a=40 Subtract 15a from both sides.


0a=40 Combine like terms on the left side.


0=40 Simplify.


Since this equation is NEVER true for any value of 'a', this means that there are NO solutions.
